Abstract: A method and a system for managing a data object so as to comply with predetermined conditions for usage of the data object. To control the usage of the data object, a set of control data, defining uses of the data object, which comply with the predetermined conditions, is created for the data object. The data object is concatenated with the user set of control data, encrypted and transferred to the user. When the user wants to use the data object, a special user program checks whether the usage complies with the control data. If so, the usage is enabled. Otherwise it is disabled.

Abstract: Embodiments provide techniques, computer-readable media, and devices for allowing users to perform interactive design of controllers, such as PID controllers, in a free-form modeling environment. Users can tune controllers using characteristics familiar to typical users rather than having to specify gain values for the controller, which may be difficult for a user to relate to the performance of a controller.

Abstract: A technique for synchronizing databases in which different techniques are used for storing a recurring event. A database in which the recurring event is, for example, stored as a single recurring record can be synchronized with a database in which the same recurring event is stored as a series of individual records. The individual records are processed to form a synthetic recurring record representing the set of individual records, and synchronization decisions are based on a comparison of the synthetic record to the recurring record of the other database. Following synchronization, the synthetic record can be “fanned” back into the individual records to update the database containing individual records, and the updated recurring record can be written back to the other database. In this way, the invention avoids the problems encountered with prior methods, in which synchronization resulted in a recurring record being transformed into a series of individual records.
